Investigation of the effect and comparison of two high-power laser treatment protocols for the improvement of clinical symptoms in patients with painful points in the upper trapezius muscle: a randomized clinical trial

Reduce patient pain

This study will be conducted in Amin Hospital of Isfahan and it is triple -blind. After selecting the samples, the participants in the study, the researcher and the analyst, are not aware of the allocation method, and the treatment is performed by the clinical caregiver who is aware of the allocation method, and the data collection is also done by them.

This study will be conducted in Amin Hospital of Isfahan and it is triple -Blind.

Inclusion Criteria: Age more than 18 years, Visual analog scale greater than 5 points, Duration of pain more than a month, Patient satisfaction to participate in the study. Exclusion Criteria: A history of cervical spine fracture and spine-related problems, Neck surgery, myelopathy or radiculopathy of the neck, Patients with perceptual disorders and pain diagnosis, Patients with myopathy and polyneuropathy, Mental illnesses or cognitive disorders, Receiving narcotics and coronet orally or intravenously, pregnancy and Blood clotting problem

Group A: In addition to standard and routine treatment. He receives 4 sessions (two sessions per week) of high-power laser (wavelength 910 nm and power of one watt as a pulse and DUTY CYCLE 80% and frequency 60 kHz). group B: In addition to standard and routine treatment. He receives 4 sessions (two sessions per week) of high power laser (wavelength 1064 nm and power of one watt as a pulse and DUTY CYCLE 80% and frequency 60 kHz). Group C: Like other groups, they receive standard and routine treatment, but for the purpose of checking the real or psychological effect of the laser, the laser is turned off and without wavelength for them is placed.

Reducing pain and disability in patients

With the easy sampling method, the referring people who are eligible to enter the study are randomly divided into three intervention, control and control groups. In this study, the classification of people is done in the form of three permutation block method. In this method, A represents the person who receives the intervention, B represents the person who is in the control group, and c represents the person in the control group. By considering the block of three, permutations are determined. Then, using the table of random numbers, we randomly select a starting point and then consider 26 numbers in rows or columns. Finally, by selecting 26 numbers from the table, the total allocation of 78 people will be divided into three groups.

After selecting the samples, the participants in the study, the researcher and the analyst are not informed about the allocation method and the treatment is done by the clinical caregiver who is aware of the treatment method and the data collection is also done by them.
